it would be prohibitively expensive and time consuming to do psychological testing and detailed background checks on every person who enters the military, including the service academies. Fact of life that there are scumbags in every group of people though by and large the military has fewer than most in the civilian world. This of course is also symptomatic of an era when young people are not being raised with the same morals and discipline as in the past; its the liberal 'me generation' that doesn't say no and doesn't demand responsibility.
